Mantis#1931. Thank you kindly, Kinoc for a patch that:
* Yield Prolog 1.0.1 Released : it passes all but 9 of the 421 tests in the ISO Prolog test suite (97.8%) . * support dynamic predicates and rules. * support 'import' to use external static functions improves connection to C# functions * Matches Yield Prolog r831

121----------- IMPORT EXTERNAL FUNCTIONS ----------
122Using 'import' to call a static function
123
124Taken mostly from http://yieldprolog.sourceforge.net/tutorial4.html
125
126If we want to call a static function but it is not defined in the Prolog code, we can simply add an import directive.
127(In Prolog, if you start a line with :- it is a directive to the compiler. Don't forget to end with a period.):
128
129:- import('', [parent/2]).
130uncle(Person, Uncle):- parent(Person, Parent), brother(Parent, Uncle).
131
132The import directive has two arguments.
133The first argument is the module where the imported function is found, which is always ''.
134For C#, this means the imported function is in the same class as the calling function.
135For Javascript and Python, this means the imported function is in the global scope.
136The second argument to import is the comma-separated list of imported functions, where each member of the list is 'name/n', where 'name' is the name of the function and 'n' is the number of arguments.
137In this example, parent has two arguments, so we use parent/2.
138
139Note: you can use an imported function in a dynamically defined goal, or a function in another class.
140
141:- import('', [parent/2]).
142uncle(Person, Uncle) :- Goal = parent(Person, Parent), Goal, brother(Parent, Uncle).
143
144:- import('', ['OtherClass.parent'/2]).
145uncle(Person, Uncle) :- 'OtherClass.parent'(Person, Parent), brother(Parent, Uncle).

166
167------------------ UPDATES -----------------
168Yield Prolog 1.0 Released : It passes all but 15 of the 421 tests in the ISO Prolog test suite.
169
170New Features:
171* Added support for Prolog predicates read and read_term.
172* In see, Added support for a char code list as the input.
173Using this as the input for "fred" makes
174set_prolog_flag(double_quotes, atom) and
175set_prolog_flag(double_quotes, chars) pass the ISO test suite.
176
177Fixed Bugs:
178* In atom_chars, check for unbound tail in the char list.
179This makes atom_chars pass the ISO test suite.
180* In current_predicate, also check for static functions.
181This makes current_predicate pass the ISO test suite.
182
183Known Issues:
184
185Here are the 9 errors of the 421 tests in the ISO test suite in
186YieldProlog\source\prolog\isoTestSuite.P .
187Some of these have a good excuse for why Yield Prolog produces the error. The rest will be addressed in a future maintenance release.
